Combine Zoning & HOLC

Further analysis questions:

1. using centroid tagging, what is the proportion of Durham zones that are represented by HOLC letters? i.e. are 80% low density homes in A grade zones?

2. what about census population, census demograhpic + income characteristics?

working progress but very interesting.
